Building Pypy

Pypy builds faster if using -O2 option.



To build faster (according to pypy documentation) use prebuilt pypy from http://buildbot.pypy.org/nightly/trunk/

Using virtualenv to create virtual environment for it.

Build script (to be placed in pypy source directory):

#!/bin/bash
cd pypy/goal || exit 1
source <path to existing pypy environment>/bin/activate || exit 2
pypy ../../rpython/bin/rpython --batch -O2 targetpypystandalone
